The effect of folic acid treatment on the post-harvest life of cucumber through influencing the activity of enzymes involved in the biosynthesis of proline, polyamine, and chlorophyll-degradation [PDF]

open access: yesفیزیولوژی محیطی گیاهی, 2022
In this study, the mechanism of cold stress tolerance in cucumber fruits pretreated with folic acid was investigated. Control group and the group treated with 5 mgL-1 folic acid were stored for 15 days at 4 °‌-C.

L-Proline Activates Mammalian Target of Rapamycin Complex 1 and Modulates Redox Environment in Porcine Trophectoderm Cells

open access: yesBiomolecules, 2021
L-proline (proline) is a key regulator of embryogenesis, placental development, and fetal growth. However, the underlying mechanisms that support the beneficial effects of proline are largely unknown.

Tributyltin (TBT) biodegradation induces oxidative stress of Cunninghamella echinulata [PDF]

open access: yes, 2016
Tributyltin (TBT) is one of the most deleterious compounds introduced into natural environment by humans. The ability of Cunninghamella echinulata to degrade tributyltin (TBT) (5 mg l-1) as well as the effect of the xenobiotic on fungal amino acids ...

Transposon mutagenesis in a hyper-invasive clinical isolate of Campylobacter jejuni reveals a number of genes with potential roles in invasion [PDF]

open access: yes, 2010
Transposon mutagenesis has been applied to a hyper-invasive clinical isolate of Campylobacter jejuni, 01/51. A random transposon mutant library was screened in an in vitro assay of invasion and 26 mutants with a significant reduction in invasion were ...

Nicotinamide Adenine Dinucleotide-dependent Proline Dehydrogenase in Chlorella [PDF]

open access: yesPlant Physiology, 1974
An NAD-linked dehydrogenase from Chlorella pyrenoidosa Chick catalyzing the conversion of l-proline to Delta(1)-pyrroline-5-carboxylic acid was partially purified. Delta(1)-Pyrroline-5-carboxylic acid was identified as the product by co-chromatography of it and its o-aminobenzaldehyde derivative with authentic compounds. The enzyme is NAD and l-proline

Variability of leaf pubescence characteristics in transgenic tobacco lines with partial proline dehydrogenase gene suppression

open access: yesBiologia Plantarum, 2022
Proline, an amino acid, plays an important role in plants, and it is involved in stress resistance and development. Earlier, to study the proline role in maintaining stress resistance in plants, we obtained genetically modified transgenic lines of ...

Regulation of osmoadaptation in the moderate halophile Halobacillus halophilus : chloride, glutamate and switching osmolyte strategies [PDF]

open access: yes, 2008
The moderate halophile Halobacillus halophilus is the paradigm for chloride dependent growth in prokaryotes. Recent experiments shed light on the molecular basis of the chloride dependence that is reviewed here.

Proline dehydrogenase is essential for proline protection against hydrogen peroxide-induced cell death

open access: yesFree Radical Biology and Medicine, 2012
Proline metabolism has an underlying role in apoptotic signaling that influences tumorigenesis. Proline is oxidized to glutamate in the mitochondria, with the rate-limiting step catalyzed by proline dehydrogenase (PRODH). PRODH expression is inducible by p53, leading to increased proline oxidation, reactive oxygen species formation, and induction of ...
